Ok, secondly, i know what you are going through. My neonate sinaloan milk snake that i bought escaped after a week. Luckely i found him under the fridge. Check everywere warm, and any nooks and crannies. Dont think that they wont travel far, because I found mine halfway across the house, and he had to travel across the cold linolium. Secondly, if you liv in a cold climate, pu an aqaurium on its side, with a pinkie mouse, hide box and heater. It may come back. If that doesnt work, put a pink mouse (actually, if you can get the shavings that the mice were kept on at the pet store, that works great!) intoa pop bottle with somthing for him to hide in (like toilet paper). CHECK EVERY NOOK AND CRANNIE!! and dont give up hope! i knew a person whos corn snake was lost for 6 months, but showed up! Best of luck!! Paul Stephen
